Lant Street history

Are their any local historians out there - I was wondering whether anyone could help? I've been asked to write a book by Ebury based on some of my ancestors. My great grandfather Alexander Crisp was a hansom cab driver living in Lant Street in the 1880's and 1890's. He drove Gladstone to Parliament and Edward VII to his mistresses. I'd love to speak to anyone who knows anything about the history of the street in these years - particularly about the brewery that was there and the Gladstone pub (e.g. why is it called the Gladstone?, seems a bit of a coincidence that it's right next door to Gladstone's driver's house….) Many thanks, Helen.
